[PATCH i-g-t v1 16/16] tests/kms_ccs: limit #crtcs tested during suspend

["Michał Grzelak" <michal.grzelak@intel.com>]

Limit execution of suspend tests to first and last active CRTC unless
using `extended` flag. This reduces default execution time of the test.
In turn this can lower chances of hitting CI timeout.
